So I finally unlocked the 18S after 125 miles, however I'm trying to wrap my head around the poor range i'm getting!

12.2 real miles (via GPS) went from 100% to 62%, riding mostly in the 17-20 MPH range, music playing through speakers. Is this what you'd consider normal?

I also found toward the middle and bottom of the battery, I have to accelerate slowly in order to prevent the wheel from tilting me back, in order to keep the tiny battery from sagging too much. I weigh about 180 lbs, 185-190 with my gear (varies).

I guess my questions are:

1. Will riding without music playing significantly improve my range?

2. Aside from riding at a slower speed, is there anything else I can do to improve my range (besides losing 30 lbs)

3. Upgrading this wheel to the 1680Wh SHOULD in essence double my range and make more of the battery's capacity usable at high speed, right?

No. The few W of the speakers make no real difference.

Losing weight is always a good ideaAs is a bigger battery. Nothing much else you can do.

Yep. And the reduced voltage drop will be extra nice, so you get a little more than 200%.

A 840Wh battery is usually good for 40-45km (25-28mi). So everything looks normal.

The "battery percentage" is just the voltage percentage between full and empty. Which is not linear, but drops fast towards low battery (and right at the start). So you cannot extrapolate your range from partial use of a battery charge. You need to do a real world range test if you want to know for sure.

I just went ahead and got the top battery from eWheels (surprisingly good price too) and upgraded to 1680Wh following eddiemoy's video. Went 30.4 miles non stop, 44% battery remaining. No more range anxiety for me!
